Pumping equipment for ventilation, air-conditioning and air-filtration systems

Pumping equipment is something that is rarely considered during the design phase, yet it is precisely this equipment that determines whether the entire system will function as intended. In this article, we’ll explore how pump units fit into HVAC systems, why heat exchange and air exchange depend directly on a correctly selected pump, and what to look out for when choosing equipment for ventilation, air conditioning and air filtration systems.

The importance of pumping equipment in ventilation and air-conditioning systems

Pump equipment in ventilation and air-conditioning systems is a vital component that keeps the entire system running. The pump circulates the coolant between components, maintaining the required pressure and flow rate. If it is incorrectly selected, HVAC systems will either consume excessive electricity or simply fail to cope with the load.

‘The experience of installation companies confirms that a correctly selected pump reduces system maintenance costs by 20–30 per cent over the first five years of operation.’

How pumps affect the efficiency of heat and air exchange

The efficiency of any climate control system depends directly on how evenly the heat transfer fluid or chilled liquid circulates. It is the pump units that regulate the speed of this circulation, which directly affects heat exchange between the pipework and the air in the room.

As for air exchange, pumps are used in humidifiers, cooling systems and heat recovery units. Without a constant flow of fluid, it is impossible to achieve an even distribution of air throughout all areas of a building.

Main types of pumps for HVAC systems and air filtration

Various types of pumps are used in ventilation and filtration systems, depending on the tasks and specific characteristics of the facility. The most common types are listed below, with a brief description of their purpose.

Pump type	Purpose	Features
Circulation	To circulate coolant in cooling circuits	Low-noise, economical
Drainage	Condensate drainage from air conditioning units	Compact, easy to install
Submersible	Pumping of liquids in humidifiers and wash filters	Resistant to aggressive environments
Multi-stage	High-pressure systems	High performance

Before selecting a pump, it is important to consider the system volume, operating pressure and coolant temperature. These parameters determine which type is most suitable. The most common applications for pumping equipment in building services systems are:

1. Circulation of coolant between the chiller and fan coils in an air-conditioning system.
2. Draining condensate from the indoor units of split-system air conditioners and central air conditioning units.
3. Supplying fluid to the humidifier nozzles in air-handling systems.
4. Pumping fluid through wet filters and scrubbers for air purification.
5. Maintaining pressure in the circuits of ground-source or air-source heat pumps.

Thanks to a wide range of modern pumps, designers can select a solution for any project.

Benefits of using modern pumping equipment in engineering systems

The installation of high-quality pumping equipment delivers tangible results from the very first months of the system’s operation. The main advantages are listed below:

• reduced energy consumption thanks to variable-frequency motor speed control;
• lower noise levels compared with outdated equivalents;
• easier maintenance due to the modular design of modern units;
• longer service intervals and a longer service life;
• the ability to integrate with building management systems (BMS).

It is worth noting that modern pump units for HVAC systems feature built-in protection against dry running, overheating and overload, which significantly reduces the risk of breakdowns.
